The invention discloses a high-power electrically-driven fracturing semitrailer with voltage transformation and frequency conversion units. The semitrailer comprises a semitrailer body, a fracturing pump and an electric motor; the electric motor and the fracturing pump are integrated; the fracturing pump is longitudinally arranged on the semitrailer body; the semitrailer body is further provided with the voltage transformation unit, the frequency conversion unit and a lubricating system; the voltage transformation unit is connected with the frequency conversion unit; the frequency conversion unit is connected with the electric motor; and the lubricating system lubricates and cools the fracturing pump. Traditional power supply equipment and fracturing equipment are optimized and fused, so that one semitrailer has the functions of power supply and fracturing, the semitrailer is more flexible and convenient in actual use, and the layout of a well site of an oil and gas field is greatly optimized; and meanwhile, the fracturing pump is longitudinally arranged, so that the length of the loading part fracturing pump on the electrically-driven fracturing semitrailer is not influenced by the transportation width of the semitrailer body, and a foundation is provided for high-power operation of the fracturing semitrailer.

    本发明公开了一种带变压变频单元的大功率电驱压裂半挂车,包括半挂车体、压裂泵和电动机,所述电动机与所述压裂泵集成为一体,所述压裂泵纵向布置在所述半挂车体上,所述半挂车体上还设有变压单元、变频单元和润滑系统,所述变压单元与所述变频单元相连,所述变频单元与所述电动机相连,所述润滑系统对所述压裂泵进行润滑和冷却。通过将传统的供电设备与压裂设备优化融合,使得一台半挂车兼具供电和压裂的功能,实际使用时更灵活方便,大大优化了油气田井场布局;同时通过采用压裂泵纵向布置,使得本电驱压裂半挂车上的上装部件压裂泵长度不受车体运输宽度的影响,为压裂半挂车作业大功率提供基础。
